Dr. Muthen, I am trying some simulation of LPA with binary distal outcome, in reference of the Appendix A in webnote15 V6. I get stuck with two problems and hope if you could help.

1) I cannot generate binary distal outcome with Auxiliary option. Is there any other option available for this? My na´ve thought is to generate continuous distal outcome ranging from 0-1, and recode it as binary by a threshold. But I have no idea how to manipulate different effect sizes of latent class on distal outcome by this way.

2) It seems external analysis is not available for AUXILIARY option. I may use MplusAutomation for analyzing the 500 simulated data. However, if it is a binary distal outcome, I need to use the manual 3-step, which means I have to calculate the classification error 500 times and generate 500 different inp files. Is that right, or any better way than this?
